MACHINE FORWINDING YARN FROM CHAINS ONTO FILLING-BOBBINS.

SPECIFICATION forming part of Letters Patent No. 573,288, dated December15, 1896..

Application filed August 13, 189 i- To aZZ whom it may concern.-

Be it known that we, HERBERT LEANDER PRATT, of Lewiston, in the countyof Androscoggin and State of Maine, and CHARLES THOMAS UPTON, of Lowell,in the county of Middlesex and State of Massachusetts, have inventedcertain new and useful Improvements in Machines for W'inding Yarn fromChains onto Filling-Bobbins, of which the fol- IO lowing is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification.

This invention relates to machines for winding yarn directly from thechain onto the tilling-bobbins for use in the shuttles for weaving, andthereby dispense with the spooling or beaming of the yarn.

In winding yarn, after the same has been dyed or bleached, directly fromthe chain onto the filling-bobbin the'individual threads of the chainhave to be separated and connected each to its respective spindle. Themachines for winding the yarn on the cop or bobbin have usually eightbanks of spindles and contain as many spindles as there are threads inthe chain. As the cops or bobbins must be wound in conical layers to thevery end of the same and must form a well-wound nose at the end to makethe cops or bobbins perfect and prevent stripping when used in theshuttle in weaving, it is essential to the practical and successful useof these machines that the tension on all the threads of the chain shallbe uniform and all soft places in the cops or bobbins avoided.

The yarn during the process of doubling, dyeing, and splittingbecomesmore or less entangled, and broken ends frequently occur in the chain.To successfully wind this yarn 40 directly on filling-bobbins, theoperation of separating the yarn strands of the chain requires to beunder the constant control of the operative, so as to prevent imperfectyarn passing through the machine. In these machines the successfuloperation of all the spindles receiving the yarn from one common source(the chain) requires mechanical refinements and automaticself-adjustments that in the ordinary spinning, twisting, or wind-Serial No. 520,132. (No model-l ing machines, in which each spindle issup plied from an independent source, are either unnecessary or not ofsuch importance as would make the machine useless without them. Inmachines for winding the thread directly from the chain on the cop orbobbin the great saving in time, labor, and mill-room has been madepossible by close attention to the details of the machines, by which theuniform speed of the spindles, the accurate adj ustment of the tensionof the yarn, the accessibility of the spindles in doffing, the startingof the machine to wind on the new bobbins after dofiing, the uniform andregular laying of the yarn on the cops or bobbins, the protection of theyarn from floss and fiber, and the other advantages are secured.

The invention consists in the peculiar and novel constructions andarrangements of the machine, as will be more fully set forthliereinafter and more particularly pointed out in the claims.

Figure 1 is a view of the end of the winding-machine and thechain-tension machine which delivers the yarn under the required tensionto the winder. Fig. 2 is a vertical sectional view of the yarn-windingmachine. Fig. 3 is a front View of the machine, in which only twovertical rows of spindles are shown, the other spindles being left offso as to show the construction of the machine more fully. Fig. 4c is atop view of the delivery-rolls, showingthe rods for concentrating thethreads when dotting in the normal posit-ion. Fig. 5 is the same view asFig. 4, showing the threads concentrated for doffing. Fig. 6 is an endview of the pinion connecting the cop-building mechanism with thedriving mechanism, showing part of the gear and the stop-link by whichthe pinion is secured. Fig. 7is aview of the shaft and pinion and asectional view of the stop-link shown in Fig. 6. Fig. 8 is a a view ofone of the spindles, partly in section. Fig. 9 is a skeleton front viewof the machine, showing two vertical rows of .spindles and guide-eyesplaced much farther apart than they are in the machine, so as to moreclearly show the paths of the severalthreads from the top rolls to theguide-eyes and the spindles and placed in the rear of the rail in frontand above the same, so that the spindles form inclined bank or slope andcan each be readily;

reached by the attendant for the purpose of doffin g or piecing.

The numbers 1 designate the end frames, and 1 the central frame,of themachine,which form the supports to which the bolster-rails 2 2 aresecured, and also the supports for the driving cylinders and themechanism by which the various parts of the machine are operated. Thecentral frame 1 is an important feature. The large number of spindlesrequire to be so closely grouped together that the driving-cylinders canbe only of limited diameter, and therefore require a central support.The bolster-rails 2 each support a line of spindles.

In Fig. 3 only two spindles are shown as secured to each bolster-rail.;but in the machine as used the spindles are placed along nearly thewhole length of the bolster-rail as close together as the practicalworking will permit.

The numbers 3 represent the spindles, the construction of which is moreclearly shown in Fig. 8 and will be more fully described hereinafter.

Numbers 4 designate the bobbins or quills on which the yarn is wound inthe shape of acop ready for use in the loom-shuttle.

5 designates the driving-cylinders turning in the bearings 6 in the ends1 and center frame 1 of the machine. Each one of the cylinders 5 is madeto operate two lines of spindles. The bands 7 7 pass partly around thedriving-cylinders 5 and the whirls of the spindles 4, so that for amachine with eight lines of spindles four driving-cylinders are used.

The machine is driven by means of a belt communicating power from aprime motor to the pulleys 8 9, 8 being a pulley secured to thedriving-shaft and .l a pulley loose on the shaft. The power istransmitted from the fixed pulley S, by means of the gears 10 and 11, tothe main driving-cylinder 5. On the opposite end of this maindriving-cylinder 5 the gears 12 transmit the power to the otherdriving-cylinders 5, so that all the drivingcylinders, and, by means ofthe driving-bands 7, all the spindles revolve with the same speed. Tothe projecting end of the shaft of main driving-cylinder 5 thesprocket-wheel 13 is secured, and from the same the chain 11 passesunder the flanged gravity-binder 14: and over the sprocket-wheel 15,secured to the shaft of the roll 18, from which, by means of the gears17 motion is transmitted to the roll 16. The top roll 10 rests on thetwo rolls 16 and 1S and turns with them. The iron center of this toproll 19 is very slender to allow it to deflect to conform to thedeflection in rolls 16 and 18, and is covered with rubber or similarelastic material to secure a firm bearing at all points of the surfaceof the rolls 16 and 18, and is then covered with felt or otherfibrg usnaterial to enable it to take u pTny broken threads. On the top of themachine, in the rear of the rolls 16, 18, and 19, is suspended the reed20 by the rods 20', connected with the upper end of the posts 20 securedone to each end of the machine, or, when convenient, from the ceiling ofthe room in which the machine is located. This movable suspended reed 20is specially made for this work and is equally spaced over its entirelength to conform to the space of the spindles.

The swinging reed 20 can be moved backward and forward by the operativeto facilitate the separation of the'threads of the chain, and when thestrain on the reed is excessive the operative stops the machine. \Vhenthe operative releases the reed, it swings toward the top rolls until itrests on the table 56. A bench is usually placed in front of thefoottreadle 36 on which the operative stands, so that when theoperative, whose hand is on the swinging reed, feels that excessivestrain is exerted on the reed he can stop the machine with his foot.

WVhen the threads require to be bunched to facilitate doffin g, the reed20 is moved back to facilitate the bunching of the threads. The point atwhich the rods 20 are pivotally connected with the posts 20 is inpractice much higher above the machine, and the reed swings through anarc of greater radius than that shown in the drawings. The rods 20 areconnected to eyes on the upper bar of the reed, so that the reed mayswing independent of the rods.

()n the projecting end of the shaft of the lowest driving-cylinder thepinion 22, provided with a groove, is connected with the shaft, whichhas a spline and turns with the same while in the normal gearedposition, and

is held in that position by the stop-link 22', which rests on the shaftbetween the nut on the end of the shaft and the pinion 22, so that whenthe stop-link is removed the pinion 22 can be drawn outward and thepinion disconnected from the gear 22 thereby disconnecting thespindle-driving mechanism from the cop-building mechanism and permittingthe winding back and independent adjustment of the cop-buildingmechanism. The chain 23 connects the sprocket-wheel on the shaft of thegear 22 with the sprocket-wheel 24, from which motion is imparted bymeans of gearing to the cop-forming mechanism by which the reciprocatingguide-wires 26 are operated. These guide-wires are secured to thehorizontal rods 27, extending from end to end and are supported on theinclined bars 27, which are in turn secured to the upright supports 29,the feet of which rest on the levers 30, which levers are provided withthe balance-weights 31, by which the cop-building guide-wires, thehorizontal rods, and the frame in which the rods are carried, as well asthe upright supports 29, can be counterbalanced or slightlyoverbalanced, so that the cop-building mechanism can operate the samewith the least practical strain. The counterbalanced levers 30 areplaced near each end and the middle of the machine and are connected soas to be operated together by the cop-building mechanism, as is shownclearly in Fig. 2.

To secure the most economic results, the machines require to be of suchlengths that the greatest number of spindles that can be attended to byone attendant are massed in one machine. To lay the yarn on all thequills or bobbins uniformly, the guide-wires must all move together. Tosecure this uniform motion of all the guide-wires, we construct a rigidframe in which the horizontal rods 27 are firmly secured to the inclinedbars 27 27 27, near the center of the machine on each side of thecenter, and also secure the ends of the rods 27 in the end bars 27 27,the whole forming a rigid frame which is sup ported 011 six'verticalrods 29, three near the front and three at the rear.

The cop-building mechanism used in this present machine is the same asthat described in Patent No. 416,495, granted to us December 3, 1889.The mechanism by which mo tion is imparted to the cop-building mechanismconsists of the cam 40, revolved by means of the-shaft carrying thesprocket-wheel 24 and intermediate gears 49 and 50. (Shown in Fig. 2.)The edge of the cam 40 bears against a stud 51, projecting from thesideof the horizontal lever 41. On the opposite side ing from the saidlever, is the pulley 42, having the worm-gear 45 secured to it. To thepulley 42 is secured one end of the chain 43, which, passing over asheave, is connected with the arm 44, mounted on the lever 30.

The cam 40 in the cop-building mechanism shown in the drawings is acircular disk secured to the shaft at one side-of the center, so as toimpart in revolving reciprocating motion to the horizontal lever 41. Aheartshaped cam may be used, so as to impart a quicker motion to theguide-frame in one direction, preferably a slow downward motion, so asto lay the yarn on the quill or bobbin in close spirals, and a quickerupward motion,

so as to bind the yarn by an open spiral binding-thread. The motion ofthe lever 41 is transmitted by the chain 43, secured to the pulley 42,to the levers 30 and by the said levers to the inclined frame 27,upright supports 29, and rods 27,1 carrying the guide wires, which arereciprocated Vertically to guide the yarn on the conical base of thebobbin, thus layin g one layer of yarn as the horizontal lever 41,operated by the cam 40, moves upward and another as it moves downward,the weight of these reciprocating parts being counterbalanced or nearlycounterbalanced by the weights 31.

By the use of the center frame 1 great stability is secured for therails 2, on which the spindles are supported, and the driving-cylindersalso are more firmly held by being journaled in bearings supported'inthe central frame. To secure the same stability to the mechanism bywhich the cops are built and the yarn'is laid on the quill or bobbin, wehave secured the rods 27 which carry the guide eyes or wires togetherand formed them into a substantial frame by the use of the three rails27 and the end rails 27 and have supported this frame on three sets ofcounterbalanced lifting-rods 29.

In a machine for winding yarn directly from the chain where the spindlesare ar ranged in. sloping banks close to each other it would bedifficult to remove and replace the quills or bobbins, as the threads ofyarn practically cover the whole of the front. To facilitate the doffingof the spindles, we support in suitable guides in the rear of the toprolls and close to the roll 16 the rods 55 and 55, as shown in Figs. 4and 5. On these rods 55 and 55 we place vertically-projecting pins, sothat the yarn of each two vertical rows of spindles passes between twopins, one on each of the rods, and we provide suitable means forshipping the rods 55 and 55, so that all the threads, namely, in amachine of the present construction, sixteen threads, leading to twovertical rows of spindles are brought or bunched together, as shown inFig. 5, be tween the two rows of spindles, and so leave wide spacesbetween the bunched threads of yarn and free access to the spindles fordofling. of the horizontal lever 41,'on a stud project- In connectionwith the devices for bunching the. threads of yarn of two vertical rowsof spindles between alternate vertical rows'of the spindles we place theguide eyes or wires for dofling the width between the bunched threads isthe width of two rows of spindles, forming a wide path which permits thetaking off of the filled bobbins and the replacing of the new emptybobbins.

We do not wish to confine ourselves to any particular means foroperating these rods 55, but have shown them each atone end pro videdwith a rack and have shown a pinion between the racks, so that byturning the pinion the bars may be operated. These. bars 55 may beshipped or operated by ha-ndor by any other suitable'means.

Practical experience has demonstrated that the reed 20 requires to beplaced near the top rolls, so as to accurately guide the yarn onto thedelivery-roll 18 and from the same to the spindles; but in bunching theyarn in dofling this close proximity of the reed to the top rollsinterferes with the bunching. We therefore suspend the reed 20 by therods 20 at each end from the vertical posts 20 extending at each endabove the end frames of the machine, so that the operator on preparingfor dofting, before he stops the machine, pushes the reed 20 backwardfrom the position shown in Fig. 4 to the position shown in Fig. 5.

The spindles 3 are driven at a speed sufficient to wind all the yarndelivered to them at the smallest diameter of the quill or bobbin and topermit the automatic adjustment and uniform tension at all diameters ofthe quill or bobbin. The bobbin is not secured to the spindle, but tothe bobbin-holder 4, which is loose on the spindle and is supported 011the whirl 3, a friction-disk 3 of felt or other suitable material, beingplaced between the whirl and the bobbin-holder. The frictionalresistance can be regulated by increas ing or diminishing the diameterof the friction-disk 3 thereby extending the frictional resistancefarther from the center or bringing the same nearer to the center ofrotation of the spindle, and the quills or bobbins will be wound asclose and hard as may be required.

The bobbin-holder 4 consists of a lower circular flange 4, from whichextends upward the cylindrical waist 4*, which curves outward to theupper flange 4, of somewhat larger diameter than the base of the bobbin.The bobbin-holder serves to hold the thread during dofling, as will bemore fully set forth hereinafter.

The machine is covered in and protected from loose ends and floss,detached by the thread passing through the reed 20, by the table 50,whichextends over the length of the machine and the whole of the width,except the front portion protected by the top rolls. The table 56 formsthe support of the end guide-bars 5G, placed on each end of the machineto form the end guides for the swinging reed 20.

The chain-tension device is placed in the rear of the machine andconsists of the frame 57, in which the two cylinders 58 and 59 arejournaled. Each of these cylinders is partially surrounded by afriction-strap, one end of which is secured to the frame 57 and theother .to one of the levers (i0, pivotally connected at one end to theframe 57 and provided at the other end with an adjustable weight. Thechain 61 passes through the eye 62, under the roll 63, over theweight-roll 64, and then between the rolls 63 and 64, under the cylinder58, then over the cylinder 59, thence two or more times around both thecylinders 58 and 59, and then over the roll 65. The chain is now splitand the individual threads passed through the reed 20 over the top rollsand to the respective spindles.

These machines are usually built of greater length than the proportionallength shown in Fig. 3, and as six, eight, or more lines of spindles arebanked above and behind each other a very large number of spindles maybe used and easily overlooked by the operative.

The machine is started and stopped by shipping the driving-belt to orfrom the driving-pulley by the shipper 32, which is connected by meansof the bell-crank 33 with the rock-shaft 34, to which the levers 35 aresecurely fastened and provided at their end in front of and extendingthe whole or nearly the whole length of the machine with the treadle 36.The weight of these levers and connecting-board is counterbalanced bythe weight 37, adjustably secured to the lever 38, which is fastenedsecurely to the rockshaft 34. g

In a machine for winding yarn from the chain onto filling-bobbins such avery large number of threads have to be separated from each other andguided to the bobbins that it becomes difficult for one operative ,tooverlook the separation of the threads and the winding on the bobbins.The vibrating threads passing through the swinging reed cannot bereadily seen without a suitable background. The table 56 forms such abackground and is used for this purpose, as also to prevent the looseends separated by the reed from falling on the threads passing from thetop rolls to the bobbins. In these machines, where as many as threehundred and seventy-six (376) spindles are used, it is impractical toconnect all the ends after doffing with the new bobbins. Somearrangement is therefore required by which all the ends areautomatically connected with the new bobbins. The arrangement which wepreferably use consists in the bobbin-holder 4 and the arrangement fordisconnecting the spindle driving mechanism from the copbuildingmechanism shown in Figs. 6 and 7. When the bobbin is completed, thestop-link 22 is removed, the gear 22 is drawn outward away from thesplineby whichit is secured to the shaft and thereby disconnected fromthe gear 22, the machine which has been stopped is started and turns allthe spindles, the frame carrying the guide-eyes is depressed until theyarn is wound around the waist 4 of the bobbin-holder 4, the belt is nowshipped and the revolution of the spindles stopped, the yarn is bunched,as before described, so as to give free access to the bobbins, and theoperative quickly jerks the bobbins off the spindles and, by reason ofthe corners of the upper flange 4 of the bobbin-holder 4, the yarneasily breaks.

\Vhen the new or empty bobbins have been placed on the spindles,thedriving mechanism is started to drive the spindles, the frame supportingthe guide-eye is raised, and the threads connected with thebobbin-holders.

are guided onto the bottom of the cone of the bobbins, the machine isstopped, the gear 22 is pushed in to connect it with the gear 22 so asto connect the cop-forming mechanism with the spindle-drivin gmechanism, the machine is started, and a new set of bobbins is wound. Bythis arrangement the operation of the machine is practically continuous,the savim eitected is large, as by reason of the improvementsincorporated in the machine the operative has a complete oversight andcontrol of the large number of threads as the yarn is delivered to thetop rolls, as well as over the whole bank of spindles, being able tostop and start the machine while his eyes are on the yarn coming fromthe chain as well as 011 the yarn being wound on the spindles. Havingthus described our invention, we claim as new and desire to secure byLetters Patent 1.
